Fedora from packages
For Fedora 22 or greater, installing the Wazuh server components entails the installation of the relevant packages after adding the repositories.
Note
All the commands described below need to be executed with root user privileges.
Adding the Wazuh repository
The first step to setting up Wazuh is to add the Wazuh repository to your server. You can download the wazuh-manager package directly or check the compatible versions in the Packages list section.
To set up the repository, run this command:
# rpm --import https://packages.wazuh.com/key/GPG-KEY-WAZUH # cat > /etc/yum.repos.d/wazuh.repo <<\EOF [wazuh_repo] gpgcheck=1 gpgkey=https://packages.wazuh.com/key/GPG-KEY-WAZUH enabled=1 name=Wazuh repository baseurl=https://packages.wazuh.com/3.x/yum/ protect=1 EOF
Note
From Fedora v22 to v25, it's required to install dkms
package (dnf install dkms
).
Installing the Wazuh manager
The next step is to install the Wazuh manager on your system:
# dnf install wazuh-manager
Once the process is complete, you can check the service status with:
For Systemd:
# systemctl status wazuh-managerFor SysV Init:
# service wazuh-manager status
Installing the Wazuh API
Note
If you have Fedora v24 or lower, you need to add the official NodeJS repository previously:
# curl --silent --location https://rpm.nodesource.com/setup_10.x | bash -
Install NodeJS:
# dnf install nodejs
Install the Wazuh API:
# dnf install wazuh-api
Once the process is complete, you can check the service status with:
For Systemd:
# systemctl status wazuh-apiFor SysV Init:
# service wazuh-api status
Note
Now that the Wazuh API is installed, check out the section Securing the Wazuh API to set up some additional settings.
(Optional) Disable the Wazuh repository:
It is recommended that the Wazuh repository be disabled in order to prevent accidental upgrades. To do this, use the following command:
# sed -i "s/^enabled=1/enabled=0/" /etc/yum.repos.d/wazuh.repo
Installing Filebeat
Filebeat is the tool on the Wazuh server that securely forwards alerts and archived events to Elasticsearch. To install it:
Add the Elastic repository and its GPG key:
# rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch # cat > /etc/yum.repos.d/elastic.repo << EOF [elasticsearch-7.x] name=Elasticsearch repository for 7.x packages baseurl=https://artifacts.elastic.co/packages/7.x/yum gpgcheck=1 gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch enabled=1 autorefresh=1 type=rpm-md EOF
Install Filebeat:
# dnf install filebeat-7.9.2
Download the Filebeat configuration file from the Wazuh repository. This is pre-configured to forward Wazuh alerts to Elasticsearch:
# curl -so /etc/filebeat/filebeat.yml https://raw.githubusercontent.com/wazuh/wazuh/v3.13.6/extensions/filebeat/7.x/filebeat.yml # chmod go+r /etc/filebeat/filebeat.yml
Download the alerts template for Elasticsearch:
# curl -so /etc/filebeat/wazuh-template.json https://raw.githubusercontent.com/wazuh/wazuh/v3.13.6/extensions/elasticsearch/7.x/wazuh-template.json # chmod go+r /etc/filebeat/wazuh-template.json
Download the Wazuh module for Filebeat:
# curl -s https://packages.wazuh.com/3.x/filebeat/wazuh-filebeat-0.1.tar.gz | sudo tar -xvz -C /usr/share/filebeat/module
Edit the file
/etc/filebeat/filebeat.yml
and replaceYOUR_ELASTIC_SERVER_IP
with the IP address or the hostname of the Elasticsearch server. For example:
output.elasticsearch.hosts: ['http://YOUR_ELASTIC_SERVER_IP:9200']
Enable and start the Filebeat service:
For Systemd:
# systemctl daemon-reload # systemctl enable filebeat.service # systemctl start filebeat.serviceFor SysV Init:
# chkconfig --add filebeat # service filebeat start
(Optional) Disable the Elastic repository:
It is recommended that the Elastic repository be disabled in order to prevent accidental upgrades. To do this, use the following command:
# sed -i "s/^enabled=1/enabled=0/" /etc/yum.repos.d/elastic.repo
Next steps
Once you have installed the manager, API and Filebeat, you are ready to install Elastic Stack.
Uninstall
To uninstall the Wazuh manager and Wazuh API:
# dnf remove wazuh-manager wazuh-api
There are files marked as configuration files. Due to this designation, the package manager doesn't remove those files from the filesystem. The complete files removal action is a user responsibility. It can be done by removing the folder /var/ossec
.
To uninstall filebeat:
# dnf remove filebeat
